BTCUSD Long after 20% dump

COINBASE:BTCUSD   Bitcoin / U.S. Dollar
I'm expecting BTCUSD to dump 20% in the short-term to about $5k by June 2020. After forming a double bottom , I do anticipate BTC to start pumping towards $15k by end of this year. After that, $100k by September 2022. I'm expecting a similar move to when Bitcoin dumped to $3.1k during December 2018.
